Seismic Wavelet Estimation─Matrix-Equation Method of High-order Cumulants
【摘要】 应用高阶累积量辨识FIR系统的方法已在众多领域得到广泛的应用研究.本文提出了一种估计地震于波方法-高阶累积量矩阵方程法.该方法在反射系数序列为非高斯、统计独立的随机过程假设条件下.适用于任意相让子波和任意加性高斯色噪声的情况,且运算时间较短,精度较为理想.模型和实际数据实验表明,该方法对于地震资料处理中的子波估计具有较好的应用前景.
【Abstract】 The methods , Which are based on FIR system identification by high-order cumulant,have been extensively and applied in many fields,In this paper,the seismic wavelet is estimated by solving matrix equation consisting of the high-order cumulant Its assumption is that the refleccient series is a non-Gaussian and stationary IID random process It is applicable for wavelet estimation of arbitrary phase and additive Gaussian clored noise The method is characterized on lighter computational burden and effective results Computer simulations and runs of filed data demonstrate that method can bed effectively used to processing of seismic data.
